To all whom t may concern.'

:Be it known thatv l Lorrains Qf-.Winsoua citizen'oi' the UnitedStatesyresidingrrat Baltimore, State ofl Maryland, have invented certainnew and useiullmprovements-in Arch-Supporting lfnsoles; and l dohereby;V

declare the following to be a full, clear, and exact description or" theinvention,.suchas` will enable others skilledV inthe art to which itappertains to make and use the same...

This invention relates to new andl ,use iul' improvements in orthopedicappliances and particularly to devicesfonuse rin the treatment of fallenarches ,A

i .One object ci the invention is to provide a device ci this characterwhich is simplein construction, and which is durable'and eii'ecA-f tivein its operation.

.another Vobject is to provide an insole for a shoe wherein the metallicarchsupporteris replaceable by others ont diierentsizes, and havingdierent arcs.

Anotherobiect is to provide va ldevice of this character wherein the .ymetallic varch weights.

A further Objectis to provide a :device of this character wherein themetallic arch v4fis] readily removable, and wherein Athe spring is alsoremovable, with, novelV means for retaining the spring in properengagement with the metallic arch member.

Other objects and advantages willbe apparent from the followingdescription when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a plan view of an insole equipped with the arch supporter.

Figure 2 is a bottom plan view of the insole, showing the means forlretaining the spring inplace.

Figure 3 is an enlarged transverse sectional view on the line 3-3 ofFigure 2.

Figure 4i is a ylongitudinal section on the line oi Figure 2.

Referring particularly to the accompanying drawing, 10 represents aninsole formed from leather, or other suitable material, and which isarranged to be placed within a shoe. Secured to the upper face of theinsole, and

covering the intermediate portion of said face, is a sheet 11, ofleather, rubber, or

spring.. 1? `of .the rrequired tension land' strength, saidspringffbeing snugly Vseated within vthe openings of the insole and ofthe plate. .n 'Formed on the platef15,andeittend ing vfat.right angles,roin the sidek oit the apertiired portion thereof, is alateral,b1-afo-v ingl arm 18, thel portions of the plate which extend A.longitudinally of the@ insole, v and from theopposite sidesQo theopening V16 serving. as braces to hold'lthe intermediate portion ofithefinsolerlongitudinally. ljivotally connected 'to' onefof thejlongitudinalportions of thefplate "lpadjacent the central i @perline la; is` an arn.1"9, the freer end'jiof. which has 'the'notchor`recess"20 'inv one sidefor engagement with the headed stud 21 eX- tending Jfrom the lower faceof the plate 15, at the opposite side of the opening 16, as

clearly seen in Figure 2.

Thus, when a spring is properly seated in the opening 16, and encirclesthe lug 18, and

the pivoted arm 19 swung across the lower f end of the spring with itsnotch receiving the headed stud 21, the spring'will'be tensioned to urgethe plate 14 upwardly against the sheetkll. The arch of the foot of thewearer is disposed on this sheet and the weight of the person causes aslight depression of the spring. The spring is of sum-1 cient strengthto yield to a slight degree, but readily supports or presses upwardlythe arch of the foot of the wearer, with .the result that the muscles ofthe arch, and of the entire foot, are relieved of the strain incident tothe ailment known as fallen arch.

Attention is. called to the act that the arch supporting plate 14 may bereadily removed and another plate of larger or smaller size substituted,the sheet of leather or rubber 11 being unattached alongtheinner edge ofthe intermediate portion thereof.

Thus, the sheet 11 and the portion Vof the insole covered thereby formsa pocket for the reception of theplates 14 of different sizes.Y Vrlhelug of any one of the plates 14,

which might be used, will be disposed in the same position relativetothe edges of the plate s o that it will readily venter the opening 12,forreceiving the spring thereon. .Y

VWhat is claimedis:

1. An Yarch `supporter including a baseV having an aperture, a flexibleretaining means on the upper side of the base, a rigid,

arch supporting member removably disposed between the' base and theflexible retaining means and engaging in said aperture, and meansreleasably supported With in said aperture and engaging the supportingmember for urging said member up- .wardly into distending relation tothe flexible means. v

2. An archsupporter including an apertured base, aV flexible retainingVmeans on the upper face of the base, a rigid arch Vsupporting memberdisposed between the flexible means and the base and having a lugdisposed in the `aperture of the base, a resilient meansv in theaperture engaging with the lug for urging the arch supporting memberupwardly against the flexible means,

and means on the lower face of the base for releasably retaining theresilient means Within said aperture.

3.Y An 4arch supporter including an insole having an opening in itsintermediate portion, an apertured bracing plate on the lower face ofthe insole and having its aperfture registering with the opening of theinsole, an arch supporting plate disposed on the upper faceof the insoleand havingk a lug disposed in the opening thereof, a coil spring withinthe brace aperture and encircling the said lug, and a movable means on`the lower face of the insole for releasably retaining the 'spring inposition to urge the plate upwardly, and a flexibleY re` taining meanson the upperV face of the insole against'which rthe said plate presses.4. An archv supporter including a base,

a removable arch supporting plate onV the base, a retaining means on thebase engaged and flexed by the said plate, means on the, .plate forengagement with the base, and reried by the. base for urging theflexibleV means and arch supporting means into arch supporting position.Y

6. An arch supporter including Va base having an aperture, a flexibleretaining.

means on the upper side of' the base, a rigid arch supporting memberremovably disposed Vbetween the base and the flexible Y. retainingmeansV and engaging in said apery ture, resilient means supported withinsaid aperture'and engaging the supporting mein-r ber for urging saidmember'upwardly into distending relation tothe flexible means, and

means movable across said aperture for re-` Y `leasablyl holding theresilient means Within the aperture.` Y 1 In testimony whereof, I ax mysignature. v f *LORRi/LINEy Q. WILSON. v
